Mr. Blasberg chooses the top 10 chicest looks from the week.

Cate Blanchett in Givenchy

Cate Blanchett in Givenchy

Cate Blanchett wearing Givenchy: Those are my four favorite words. Who else remembers the amazing lilac Givenchy dress she wore to the Oscars in 2011? Well, Cate turned back to Riccardo Tisci to dress her for a cocktail party in New York, and she still had that magic. The overall effect was sexy but not slutty, and she looked entirely contemporary but not standoffish.

Sarah Jessica Parker in New York City

Sarah Jessica Parker in New York City

It’s such a familiar image — Sarah Jessica Parker frolicking around New York in something fun and fabulous. Paging Carrie Bradshaw! (That reminds me: Does anyone know if they’re for sure doing a third Sex and the City movie?) At any rate, this romper reminds me of what made SJP a style icon in the first place: chic, sophisticated and short. And I love that even when she’s on the go, even when she’s in a romper and carrying a day bag, nothing is going to get her out of a stiletto. A girl after my own heart.

Gretchen Mol in Bottega Veneta

While I adored the little white romper SJP wore to run around Manhattan, I was equally excited by the LBD that Gretchen Mol, seen most recently on Boardwalk Empire wore to a Bottega Veneta event in New York. It was clean, lean and sexy for the summer. Bonus points for those strappy sheer pumps.

Chloe Sevigny in LA

I’ve been a longtime fan and friend of Chloë Sevigny. (I’ve also been her dance partner, curiously enough...in case you haven’t seen it.) The basis for that obsession, of course, has been her quirky and individual sense of style. She pushes the envelope, and I can’t help but respect a woman who takes risks and has fun with fashion. For instance, some girls may be scared by a busy-printed all-in-one jumpsuit, especially when pounding the pavement in L.A., a town where comfort often replaces couture. Yet there she was, looking absolutely divine.

Gwen Stefani in Blumarine

Speaking of unique rebels, behold my teenage crush, Gwen Stefani. For legions of No Doubt fans around the world — Gwenaloonies like myself — this is an exciting time: After a 10-year hiatus, the band has reunited and is releasing a new record. You know what that means: promotional appearances. Oh, goodie! This was one of Gwen’s first stops on the promo tour, and I loved what she stepped out in, an allover animal-print Blumarine suit. It’s the full package with her — the red lip, the blonde hair, the ska attitude and the looks that don’t stop. Don't forget to look for her on the September cover of BAZAAR!

Dree Hemmingway at The Campaign NYC Premiere

People often say that the ’70s are a trend. But for a few women, they aren’t so much a trend as a regular way of dressing. Dree Hemingway, great-granddaughter of the famous writer, and a part-time-model-turned-actress, is one of those girls. I love these high-waisted, flared jeans because they seem so her.

Kate Bosworth in LA

This is definitely shorts weather, ladies. And look no further than Kate Bosworth to see how to make cool seem so effortless: Strappy flat sandals, a fun printed short, and a basic sleeveless button-down. Not that she went scrappy with her look when it came to the accessories. Her giant Tom Ford bag has just the right amount of hardware for a fashionable chick.

Kristen Stewart in Roberto Cavalli

Oh, Kristen Stewart. She’s been in the news quite a lot this week, and not for the sorts of reasons most young actresses would want to be. But I’m not here to judge a woman on anything apart from what she’s wearing, right? So in that respect, I’m happy to say that the beautiful little cheater looked fabulous in this Cavalli suit jacket. In the show it was worn as an entire suit, but I like how she paired it with black leather pants to make it her own. It’s a tough look for a girl who I expect is feeling pretty tough right now.

Jessica Alba in Narciso Rodriguez

Jessica Alba is one of the most beautiful women in Hollywood. Up close, that cinnamon skin sparkles like a dusty diamond. (I have to find out what body shimmer she uses.) And she’s never not glamorous — here she is sauntering down the sidewalk looking every bit the goddess. However, it should be pointed out that she’s wearing a fabulous Narciso Rodriguez frock and white pumps, so it’s not like she’s dressing down. But if I looked like Jessica Alba, I’d wear this to pick up a gallon of milk too.

Rosie Huntington-Whiteley in London

Rosie Huntington-Whiteley has been lying low lately, which is why I was so happy to see her out and about with her man, Jason Statham, in London. She was one of my favorite fashionable females of last summer because the girl knows how to do effortlessly buxom glamour at the drop of a hemline. I loved what Rosie was wearing this particular night: floral dress but slit to there, and scrunchy boots. Throw in a perfectly tousled mane and those perfectly pouted lips, and she’s good to go — anywhere!
